The document discusses several recent court cases regarding payment provisions in construction contracts under the Local Government, Economic Development and Construction Act 2009. The cases have clarified that if a party fails to issue payment or pay less notices, the other party can issue their own notice claiming the amount due. However, more recent cases have found that for a notice to be valid and enforceable, it must meet strict requirements regarding form, substance, and intent, and be issued in accordance with the contract. If these requirements are not met, failure to issue contrary notices does not automatically entitle the claiming party to payment.
